SLCO1B1APOE基因多态性检测性能验证

摘要

Objective To verify the performance characteristics of the human SLCO1B1 & APOE gene detection kit (PCR-fluorescent probe technique).Methods The verification protocol for the human SLCO1B1 & APOE gene detection kit manufactured by Wuhan YZY Medical Science and Technology Co.,Ltd.was designed by referring to the requirements of professional standard and pertinent literatures,and its accuracy,specificity,lowest detection limit and anti-interference ability were compared with those of sequencing technique (gold standard).Results The results coincidence of 20 clinical samples from fluorescence PCR and sequencing technique was 100％,which met the requirement of accuracy.Forty clinical samples with wild type loci determined by fluorescence PCR were verified by sequencing and no any mutation was detected,which met the requirement of specificity.The lowest detection limit of the kit was 10 ng/μL.Three interfering substances,including hemoglobin,bilirubin and triglyceride,were individually added into the blood samples with known genotype,and the results determined by the kit were coincident with that without interfering substances,which met the requirement of anti-interference ability.Conclusion The verification parameters of the human SLCO1B1 & APOE gene detection kit are basically consistent with the manufacturer's statement,indicating that the kit meets the requirements of the relevant quality management and may be applied to the detection of clinical samples.%目的 对人类SLCO1B1 &APOE基因检测试剂盒(PCR-荧光探针法)进行性能验证.方法 参照产品行业标准要求及相关文献,设计验证方案,对武汉友芝友医疗公司生产的人类SLCO1 B1 &APOE基因检测试剂盒的准确性(与金标准测序法结果比较)、特异性、最低检出限和抗干扰能力4个方面进行性能验证.结果 20个临床样本的荧光定量PCR检测结果与测序法结果比对,符合率为100％,满足试剂准确性验证要求;40个临床样本荧光PCR野生型位点的检测结果用测序方法均未检出突变,满足试剂特异性验证要求;基因检测试剂盒的最低检出限为10 ng/μL;血红蛋白、总胆红素和三酰甘油3种干扰物质加入已知基因型结果的血液样本后进行检测,与对照组结果均符合,满足试剂抗干扰能力验证要求.结论 人类SLCO1 B1 &APOE基因检测试剂盒各项性能验证参数与厂家声明基本一致,符合相关质量管理要求,可应用于临床标本检测.
